Abstract

The problem of steady boundary layer flow past a stretching wedge with the velocity in a nanofluid and with a parallel free stream velocity is numerically studied. It is assumed that at the stretching surface the temperature and the nanoparticle fraction take the constant values and , respectively. The ambient values (inviscid fluid) of and are denoted by
and , respectively. The boundary layer governing partial differential equations of mass, momentum, thermal energy, and nanoparticles recently proposed by Kuznetsov and Nield (2006, 2009), are reduced to ordinary differential equations along with the corresponding boundary conditions. These equations are solved numerically using an implicit finite-difference method for some values of the governing parameters, such as , , , , , and , which are the measure of the pressure gradient, moving parameter, Prandtl number, Lewis number, the Brownian motion parameter, and the thermophoresis parameter, respectively.
